businesses of Arden Hills, as well as people passing through the City. The proposed antennas would be at a height of 175 feet. The applicant has submitted an application, coverage analysis, engineer letter, and site survey (Attachment D). Discussion Zoning Regulations The approval of this application is contingent on approval of Planning Case 09-023, which would bring the tower into conformance with the Zoning Code and the original CUP. If Planning Case 09-023 is approved, this application would meet all zoning regulations. To add new antennas to the tower, the Zoning Code requires a CUP Amendment. According to the Zoning Code, new antennas shall be located on City water tower sites unless the applicant shows, to the reasonable satisfaction of the City, that this is not feasible. If it is established that the City water tower sites are not feasible, the Zoning Code lists alternate locations, in order of preference, for antennas. The first preference in the Zoning Code, after City water tower sites, is existing towers or structures located within any Industrial, Civic- Center, or Business District zoned property. The applicant has submitted a letter and coverage map addressing the use of the water tower sites. According to the applicant's engineer, the height and location of the City water tower sites are such that a gap in coverage would exist without the use of the Reiling Tower (Attachment D). The proposed site is located in the I-1 Industrial District. The antennas would be located on the existing tower eliminating the need to construct a new tower, which would meet the secondary location requirement of the Zoning Code. Enginee�ing Review The City has contracted with OWL Engineering to verify the information provided by Clear Wireless and conduct a coverage analysis of the proposed location compared with the City water tower sites. The consultant prepared coverage analysis maps that indicate that there would be diminished or lack of coverage in some areas if either City water tower site was used as opposed to the proposed site. The consultant also supplied a letter explaining why his coverage maps differ slightly from the coverage maps prepared by Clear Wireless (Attachment B). The consultant's conclusion was that his maps did not take into consideration seasonal foliage and building penetration, which was likely considered by Clear Wireless. The impacts of these variables would impact the look of the coverage maps; however, he felt that the underlying conclusion between the two analyses was the same.
